Inter-Fork Strand Annealing causes genomic deletions during the termination of DNA replication

open access: yeseLife, 2017
Problems that arise during DNA replication can drive genomic alterations that are instrumental in the development of cancers and many human genetic disorders. Replication fork barriers are a commonly encountered problem, which can cause fork collapse and

Dna2 Helicase/Nuclease Causes Replicative Fork Stalling and Double-strand Breaks in the Ribosomal DNA of Saccharomyces cerevisiae [PDF]

open access: yes, 2003
We have proposed that faulty processing of arrested replication forks leads to increases in recombination and chromosome instability in Saccharomyces cerevisiae and contributes to the shortened lifespan of dna2 mutants. Now we use the ribosomal DNA locus,

The COMPASS subunit Spp1 protects nascent DNA at the Tus/Ter replication fork barrier by limiting DNA availability to nucleases

open access: yesNature Communications, 2023
Homologous recombination factors play a crucial role in protecting nascent DNA during DNA replication, but the role of chromatin in this process is largely unknown.

When replication forks stop [PDF]

open access: yesMolecular Microbiology, 1994
SummaryDNA synthesis is an accurate and very processive phenomenon, yet chromosome replication does not proceed at a constant rate and progression of the replication fork can be impeded. Several structural and functional features of the template can modulate the rate of progress of the replication fork.

Opposing Roles of FANCJ and HLTF Protect Forks and Restrain Replication during Stress

open access: yesCell Reports, 2018
Summary: The DNA helicase FANCJ is mutated in hereditary breast and ovarian cancer and Fanconi anemia (FA). Nevertheless, how loss of FANCJ translates to disease pathogenesis remains unclear.

Translesion synthesis in mammalian cells [PDF]

open access: yes, 2006
DNA damage blocks the progression of the replication fork. In order to circumvent the damaged bases, cells employ specialized low stringency DNA polymerases, which are able to carry out translesion synthesis (TLS) past different types of damage. The five

Replication termination without a replication fork trap [PDF]

open access: yesScientific Reports, 2019
Abstract Bacterial chromosomes harbour a unique origin of bidirectional replication, oriC . They are almost always circular, with replication terminating in a region diametrically opposite to oriC , the terminus. The

The NuA4 acetyltransferase and histone H4 acetylation promote replication recovery after topoisomerase I-poisoning

open access: yesEpigenetics & Chromatin, 2019
Background Histone acetylation plays an important role in DNA replication and repair because replicating chromatin is subject to dynamic changes in its structures. However, its precise mechanism remains elusive.

SDE2 integrates into the TIMELESS-TIPIN complex to protect stalled replication forks

open access: yesNature Communications, 2020
The fork protection complex (FPC), including the proteins TIMELESS and TIPIN, stabilizes the replisome to ensure unperturbed fork progression during DNA replication.

Mechanisms and regulation of replication fork reversal. [PDF]

open access: yesDNA Repair (Amst)
DNA replication is remarkably accurate with estimates of only a handful of mutations per human genome per cell division cycle. Replication stress caused by DNA lesions, transcription-replication conflicts, and other obstacles to the replication machinery must be efficiently overcome in ways that minimize errors and maximize completion of DNA synthesis.
